What is Cancer?
 Cancer is a term used for diseases in which abnormal
cells divide uncontrollably and creates lumps or masses
of tissue called “tumors”.
This is a skin cancer cell
Attacking the red blood cells.

tumor is created.
What Causes Cancer ?
 Cancer begins when healthy
cells do not stop dividing.
Cancerous cells typically
divide more quickly than
(normal) cells.
 Cancer starts off as a regular
cell. Most cells have an
expected life cycle of growth,
reproduction, and death.
Preventions/Treatments
Some preventions of cancer are:
•
Every time you go to the bathroom, stop by the kitchen or water-cooler for a glass of water.
•
Another way to prevent Cancer is to take up a tea habit.
•
Some other way to prevent Cancer is to eat some Kiwi
•
Also , just make lemonade or limeade.
Treatment
•
Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells For
Example: X-rays, gamma rays, and charged particles are types of radiation used for cancer
treatment.
•
Cancer vaccines are designed to boost the body’s natural ability to protect itself, through
the immune system, from dangers posed by damaged or abnormal cells such as cancer
cells.
•
There are many other ways to treat cancer…

Some types of cancers are:
Lung Cancer
Stomach Cancer
Leukemia
Breast Cancer
Bladder Cancer
Lymphoma Cancer
Pancreatic Cancer
How CANCER affects the
cell?
 The tumor is considered not to be harmful. It can be easily removed
and will not spread to other organs. The possibility for this tumor to
reappear is much reduced.
 Cancer determines cells to divide in an uncontrollable way.
Generally the cells of the body divide only when needed, like when
they grow old and other cells need to be produced in order to
replace them or when they are in a small amount and the body
needs more of them.
History of Cancer
 The world's oldest documented case of cancer hails from
ancient Egypt, in 1500 B.C.E. The details were recorded
on a papyrus, documenting 8 cases of tumors occurring
on the breast. It was treated by cauterization, a method
to destroy tissue with a hot instrument called "the fire
drill." It was also recorded that there was no treatment
for the disease, only palliative treatment.
 There is evidence that the ancient Egyptians were able to
tell the difference between malignant and benign tumors.
According to inscriptions, surface tumors were surgically
removed in a similar manner as they are removed today.
Signs/Symptoms
 One sign of cancer is feeling weak/ or tired.
 Another sign of weight gain or loss with unknown reason.
 Some other signs or symptoms are : hard time swallowing ; or you
may have sores that don’t heal.
 Sometimes, cancer cells release substances into the bloodstream that
cause symptoms which are not usually linked to cancer. For
example, some cancers of the pancreas can release substances that
cause blood clots in veins of the legs.

Some lung cancers make hormone-like substances that raise blood
calcium levels. This affects nerves and muscles, making the person
feel weak and dizzy.
History of Cancer
 Cancer-specific survival: This statistic calculates the percentage of
patients with a specific type and stage of cancer who have
survived—that is, not died from—their cancer during a certain
period of time (1 year, 2 years, 5 years, etc.) after diagnosis. Cancerspecific survival is also called disease-specific survival. In most
cases, cancer-specific survival is based on causes of death in medical
records, which may not be accurate.
 The prognosis of a patient diagnosed with cancer is often viewed as
Diagnosis of Cancer
 There is no single test that can accurately diagnose
cancer. The complete evaluation of a patient usually
requires a thorough history and physical examination
along with diagnostic testing. Many tests are needed to
determine whether a person has cancer, or if another
condition (such as an infection) is mimicking the
symptoms of cancer.
Prognosis Of Cancer
 A prognosis is an estimate of the likely course and outcome of a
disease. The prognosis of a patient diagnosed with cancer is often
viewed as the chance that the disease will be treated successfully and
that the patient will recover.
 Cancer-specific survival: This statistic calculates the percentage of
patients with a specific type and stage of cancer who have
survived—that is, not died from—their cancer during a certain
period of time (1 year, 2 years, 5 years, etc.) after diagnosis. Cancerspecific survival is also called disease-specific survival. In most cases,
cancer-specific survival is based on causes of death in medical records, which
may not be accurate.
